Restore Your 8-pn 5500 Tsurumi Pump to Full Pumping Capacity The Aquascape 8-pn 5500 Impeller is a factory-specification replacement impeller for the Tsurumi 8-pn 5500 external pond pump. As the primary flow-generating component, the impeller is the most wear-critical part in any centrifugal pump; replacing it with an OEM-specification part returns the pump to its rated output without the cost and lead time of full pump replacement. OEM Impeller for Professional-Grade Pump Performance The Tsurumi 8-pn 5500 is a professional external pump used in demanding large-pond and water-feature applications. Its impeller is engineered to tight tolerances that directly affect pumping efficiency. Third-party aftermarket impellers often fail to match these tolerances, resulting in reduced flow or increased power draw. Using this Aquascape OEM impeller ensures the pump returns to original specification.
